Sure. But [xf86-video-]radeonhd is approximately 3x slower than [xf86-video-]ati. This is what I experienced with an ATI Radeon Mobility X1400 (RV515). unfortunately there are freeze conditions with the latter...

What do I need to do to make DRI work with this driver? I have installed radeonhd and configured xorg.conf to use it. This is working (my screen res. does end up correct and glxgears does run at about 1250 fps) but according to glxinfo, dri is not enabled.

Everything has been compiled with dri use flag.

1250? Wow! Normally you don't have anything special to do except enabling DRI but this is something common for most ATI cards. Depends on whether you're using a recent Xorg but all I had to do was add that section to xorg.conf:

Thanks - I'll try this when I get home, tonight.

I don't have the DRI section in xorg.conf - atm it's just a default xorg.conf with "vesa" replaced with "radeonhd" - I'm working on a new install.

I unmasked the whole ~amd64 branch but I haven't updated X since that - I think I'm currently on 7.2.

I'll look for mesa. I do recall glxinfo listing Mesa in the first few lines of output, before all the supported GL_ constants.

After doing a full update of world and explicitly emerging mesa and xorg-x11, I have achieved DRI! I have also managed to resolve all AIGLX warnings and errors in Xorg's log.

glxgears runs smoother, now, but reports a lower frame rate. I think the earlier one was incorrectly reported.

All that's left to do is get Compiz up on my XFCE box instead of XFWM.

Out of curiosity, what frame rate does glxgears now prompt?

Just under 700 on my X1900XTX with a bunch of stuff running - I wasn't in proper benchmark mode.

VinzC: Did you just happen to be running the unstable versions of X.org and mesa, or did you upgrade in order to get DRI working? I'm on the stable versions of both packages now. I really don't want to de-keyword xorg-x11 unless I've got no other choice.
